A system for use in providing a load on a bearing mounted to a shaft includes a preload apparatus having a first extension and a second extension engageable with an inner race of the bearing and configured to provide a compressive load to the bearing. The first extension has a first projection and the second extension has a second projection. A stop ring is configured to limit a radially inward movement of the first extension and the second extension toward each other to position the first projection and the second projection relative to the bearing.

A bicycle rear sprocket adapter comprises a plurality of external spline teeth and a plurality of internal spline teeth. The plurality of external spline teeth is configured to engage with a bicycle rear sprocket assembly. The plurality of internal spline teeth is configured to engage with a bicycle hub assembly. At least two internal spline teeth of the plurality of internal spline teeth are circumferentially arranged at a first internal pitch angle with respect to a rotational center axis of the bicycle hub assembly. The first internal pitch angle ranges from 10 degrees to 20 degrees.

A roller has a wheel, a wheel axle and a pin which protrudes upward from a housing of the roller. A sleeve sits on the pin and is spaced apart from the pin radially and axially upward by a damping material arranged between the sleeve and the pin, the damping material being arranged so that all axial and/or radial contact between the pin and the sleeve is prevented. Alternatively, an attachment damping part can be arranged on a pin of the roller in overlap with the pin, wherein the attachment damping part has an inner sleeve and an outer sleeve, the inner sleeve being spaced apart radially and axially upward by a damping material arranged between the inner sleeve and the outer sleeve. The damping material is arranged in such a way that all axial and/or radial contact between the inner sleeve and the outer sleeve is prevented.

A disc brake hub and rotor assembly for a heavy-duty vehicle. The disc brake hub and rotor assembly includes a hub receivable on and rotatable about an axle spindle of a heavy-duty vehicle. A rotor is connectable with the hub for rotation with the hub. The rotor includes a disc segment, a flange mounting segment, and a cylindrical sleeve segment connecting the disc segment and the flange mounting segment. A flange is connectable with the flange mounting segment and separately with the hub. The flange mounting segment of the rotor has an inboard facing surface at least part of which is for engaging head portions of wheel studs. The inboard facing surface is substantially planar and free of wheel stud clearance reliefs. A transition region is located between the flange mounting segment and sleeve segment and is also free of wheel stud clearance reliefs.

A vehicle wheel having a rim, a hub, a plurality of spokes with at least one of the spokes having a first portion connected the rim and a second portion connected to the hub. The rim includes a spoke bed wall with a radially outboard surface and a spoke hole having a radially outboard entrance and perimeter edge. The spoke extends through the spoke hole and is engaged to the spoke bed wall by an overlie engagement at a bearing interface between a bearing surface of the spoke and the radially outboard surface to limit longitudinally inward displacement between the spoke and spoke bed wall. At least a portion of the bearing interface is laterally outwardly spaced from the first perimeter edge by a lateral distance of at least 0.7 millimeters.

A bicycle hub assembly comprises a sprocket support body. The sprocket support body includes at least ten external spline teeth configured to engage with a bicycle rear sprocket assembly. Each of the at least ten external spline teeth has an external-spline driving surface and an external-spline non-driving surface.

The present disclosure relates to a caster, having a housing, having an axle pin which is arranged in a housing opening which is oriented substantially horizontally, and on which at least one wheel is mounted, having, at the top, a pin opening oriented substantially vertically, for receiving a pivot pin, and having a braking device which brakes the at least one wheel, wherein the housing opening for the axle pin allows limited vertical displaceability of the axle pin and the braking device comprises at least one resilient housing part which acts on the axle pin. In order to provide a mechanically reliable braking device, the braking device is additionally provided with at least one spring element which cooperates with the at least one resilient housing part and amplifies the effect of its braking force and/or increases the mechanical load-bearing capacity of the at least one resilient housing part.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

The invention is directed to a method for producing a rim (2) comprising at least one three-dimensionally shaped layer of reinforcing fibers (26). In a first step a forming tool (25) is provided which comprises a three-dimensionally shaped outer contour. In a subsequent step a band of reinforcing fibers (26) is wound onto the forming tool (25) such that the reinforcing fibers follow the outer contour of the forming tool (25) and are arranged in at least one of reinforcing fibers. A draping device (27) is provided by which the band of reinforcing fibers (26) is preformed before the band of reinforcing fibers (26) is wound onto the forming tool (25).

According to the present invention, when a first point (P1) is set on an end edge on an outer end portion (15a) side of a coupling member (15) and a fifth point (P5) is set on an end edge on an inner end portion (15b) side of the coupling member (15), and when a distance (H1) from the fifth point (P5) to the second point (P2) along a reference straight line (RL) passing through the first point (P1) and a tire axis is set to 0.80 times a reference distance (H) from the fifth point (P5) to the first point (P1) along the reference straight line, a distance (H2) from the fifth point (P5) to the third point along the reference straight line is set to 0.65 times the reference distance (H), and a distance (H3) from the fifth point (P5) to the fourth point (P4) along the reference straight line is set to 0.30 times the reference distance (H), the third point (P3) is disposed on the other side in the tire circumferential direction of an overall inclined straight line (SL) passing through the first point (P1) and the fifth point (P5), and a horizontal distance (D2) between the second point (P2) and the third point (P3) in a perpendicular direction (D) perpendicular to the reference straight line (RL) is larger than each of a horizontal distance D1 between the first point (P1) and the second point (P2) in the perpendicular direction (D) and a horizontal distance (D4) between the fourth point (P4) and the fifth point (P5) in the perpendicular direction (D).
